Be the further optimization and/or improvements to above-mentioned model utility technological scheme below:
In the above-mentioned plate hole lining can be installed, the outside right part of lining is sleeved in the plate hole, the outside left part of lining has annular boss, the left side of annular boss is concordant with the left side of lining, the right-hand member of bolt head is pressed on the left side of annular boss, and the right side of annular boss is pressed on the left side of pressing plate.
Between above-mentioned workpiece right-hand member and the installation seat plate left end clamp can be arranged, on the clamp of corresponding fitting seat hole site the clamp hole be arranged, the screw rod right part passes the clamp hole and is sleeved in the fitting seat hole.
The utility model reasonable and compact in structure; easy to use; when it bears overload strength; the shearing of workpiece makes safety bolt in left groove and the fracture of right groove; protect the higher pressing plate of cost, workpiece and installation seat plate etc. to be connected component by sacrificing lower-cost safety bolt, have safe, laborsaving, easy, characteristics of high efficiency.
Description of drawings
Accompanying drawing 1 is looked the sectional structure schematic representation for the master of the utility model most preferred embodiment.
Coding in the accompanying drawing is respectively: 1 is pressing plate, and 2 is workpiece, and 3 is installation seat plate, and 4 is nut, and 5 is bolt head, 6 is screw rod, and 7 is plate hole, and 8 is workpiece hole, and 9 is the fitting seat hole, and 10 is left groove, 11 is right groove, and 12 is lining, and 13 is annular boss, and 14 is clamp, and 15 is the clamp hole.
Embodiment
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description 1 is described, as: the position relation of forward and backward, upper and lower, left and right etc. is what to determine according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this safety bolt connection set comprises safety bolt, pressing plate 1, workpiece 2, installation seat plate 3 and nut 4; Safety bolt comprises bolt head 5 and screw rod 6, the right-hand member of bolt head 5 and screw rod 6 left ends are connected as a single entity, pressing plate 1, on workpiece 2 and the installation seat plate 3 plate hole 7 is arranged respectively, workpiece hole 8 and fitting seat hole 9, right-hand member clamping platen 1 left end of bolt head 5, screw rod 6 passes plate hole 7 from left to right successively, workpiece hole 8 and fitting seat hole 9 and to extend installation seat plate 3 right-hand, there is left groove 10 at screw rod 6 middle parts of corresponding workpiece hole 8 left positions, there is right groove 11 at screw rod 6 middle parts of corresponding workpiece hole 8 right end position, there is screw thread in the right part outside of screw rod 6 and is installed with nut 4, and nut 4 left ends are pressed on installation seat plate 3 right sides.When workpiece 2 bears overload strength; the shearing of workpiece 2 makes safety bolt in left groove 10 and the fracture of right groove 11 places; protect the higher pressing plate of cost 1, workpiece 2 and installation seat plate 3 etc. to be connected component by sacrificing lower-cost safety bolt, thereby loss is dropped to minimum.
